(Cl. 19d-itl) This invention relates to improvements in coin changers. More particularly, this invention relates to improvements in coin changers which can accept coinage and send an impulse to a vending machine, and which can return change if the coinage has a value in excess of the sales price.

It is therefore an object of the present invention to provide an improved'coin changer which can accept coinage and send an impulse to a vending machine, and which can return change if the coinage has a value in excess of the sales price.

This invention is an improvement on the invention shown and described in our co-pending application Serial Number 620,281 which was filed November 5, 1956 and which was granted March 26, 1963 as Letters Patent No. 3,082,852.

In the operation of the coin changer in said co-pending application, the inserted coins engage the actuator of the motor-controlling switch and hold that actuator in motor-energizing position throughout the first part of the cycle of operation of that coin-operated device. This means that there must be a closely-held dimensional and positional relationship between the coin passageways, the path of movement of the switch actuator, and the coinresponsive elements of the coin changer. In the coinoperated device of the present invention, a magnet is provided which holds the actuator of the motor-controlling switch in motor-energizing position during the first part of the cycle of operation of the coin changer and thereby obviates the need for a closely-held relationship between the coin passageways, the path of movement of the switch actuator, and the coin-responsive elements.

The magnet which holds the actuator of the motor-controlling switch is mounted on a lever which has an abutment; and that abutment is spaced from the magnet. Further, that abutment cooperates with the magnet to confine that switch actuator between them. The spacing between that magnet and that abutment is such that inserted coins can move the switch actuator from motor tie-energizing position to motor-energizing position without requiring any movement of the lever on which that magnet and that abutment are mounted. Further, the spacing between that magnet and that abutment is such that the lever can subsequently move downwardly and place the abutment in position to hold the switch actuator in motor-energizing position. That lever can remain in lowered position and enable that abutment to hold the switch actuator in motorenergizing position until the end of the cycle of operation of the coin-operated device. As a result, the lever and its abutment and magnet can hold the switch actuator in motor-energizing position throughout an entire cycle of operation; and they do not require inserted coins to do more than move the switch actuator to motor-energizing position.

The coin changer provided by the present invention is a change-making device which utilizes a payout slide with a thickness somewhat less than the thickness of a nickel. Where the sales price of the article to be vended is five cents, and a quarter is inserted, that payout slide will be reciprocated tour times to pay out four nickels as change; and where the sales price of the article to be vended is tive cents, and a dime is inserted, that payout slide will be reciprocated once to pay out one nickel as change. Where the sales price of the article to be vended is ten cents, and a quarter is inserted, it is only necessary to return three nickels as change; and Where the sales price of the article to be vended is ten cents, and a dime is inserted, no nickels should be paid out as change. The present invention provides a change-making device that can, with an exceedingly simple adjustment, beset for a ve cent or a ten cent sales price. The present invention does this by providing a cam with one of the lobes thereof movable relative to the rest of the lobes, and by using screws to secure that lobe tothe cam.

ln the manufacture of the change-making device of the present invention, it is desirable to form a large number of the relatively movable parts with punch presses. In the forming of parts with punch presses, burrs on the parts are unavoidable. Heretofore, those burrs have had to be removed by holding each relatively movable part adjacent a sanding belt or an abrasive wheel; and this involves extra handling of those parts and thereby .increases the cost of the change-making device. The present invention obviates all need of sanding or grinding the parts, and of the resulting extra handling of those parts, by providing those relatively movable parts with ribs that permit those parts to move freely relative to each other despite the presence ot the burrs.

The present invention has two coin-responsive elements that intercept, and that subsequently hold and feel, inserted coins; and those coin-responsive elements determine when and how many nickels are paid out as change. Toenable those coin-responsive elements, and other elements of the change-making device to be made inexpensively by mass vproduction methods, the present invention provides a gauging lever that precisely lixes the coin-holding positions of those coin-responsive elements. ln doing so, that gauging lever avoids premature and accidental freeing of the coins from the coin-responsive elements.

That gauging lever has two abutments that are spaced apart both horizontally and vertically, and those abutments can be moved into and out of register with an abutting surface on one of the coin-responsive elements. When one of those abutments is in register with that abutting surface on that coin-responsive element, the coin-responsive elements can be moved a predetermined distance away from coin-feeling position; and when the other of those abutments is in register with that abutting surface on that coin-responsive element, the coin-responsive elements can be moved a second and greater predetermined distance away from coin-feeling position. When both of those abutments are out of register with that abutting surface on that coin-responsive element, the coin-responsive elements can be moved still further away from coinfeeling position. f

The payout slide of the present invention is biased to coin-discharging position by springs, and it is moved away from coin-discharging position by the lobes of the cam. The springs, which bias the payout slide toward coin-discharging position, urge that slide against the lobes of the cam and thereby bias that cam for rotation in a direction opposite to its normal direction of rotation. Such opposite rotation could permit the payout slide to move to coin-discharging position and pay out an extra coin; and hence, such opposite rotation of the cam would be very objectionable and must belimited. The present invention limits such opposite rotation of the cam by providing that cam with a number of notches or abutments and by providing a latch that is engageablewith those notches or abutments to limit opposite rotation ofthe cam. That latch and-those notches or abutments permit unlimited rotation of the cam in its normal and desired directior'i, but closely limit'rotation of posite direction.

A Yilange 211 is provided at the rear edge of .the plate 2019", and that'fiange extends downwardly and rearwardly towardV the bottom n wall 140; as shown particularly byv FIG. 3. That flange stiifens the plate 211. llange 212 extends upwardly around an'openingV at the center of the supporting plate 209, and that ange accommodates the lowerendot -a bottom wall 140 and the lower face, of supporting plate Y 200. That spacing exceeds'the thickness of slide 174 plus the combinedheights of ribs 146 and 176; and hence that i spacing facilitates Vfree recip'rocation Vof the slide 17 4. AsV

the slide 174.reciprocates, the ribsll-id, 145, and 154 on bottom wallldil and the ribs 176 on that slide min` v imize frictional resistance to that reciprocationand alsoV keep4` the burrs fromccvyntactingntlley bottom wall 144i) or the supporting plate 200. The springs 2,16 extendbetween After .I

That pin is held in position within the openings in the upper portions ot the ears 184 by the n the openings in the ends of pin 186 and openings in the L-shaped bracket 179, and those springs bias the slide 174 for movement toward the resilient pad 168.

The numeral 222 generally denotes a lever which is rotatably mounted on the pivot 62 adjacent the left-hand side of FIG. 1. That lever has a hub 224 with an opening that telescopes over the pivot 62, it has a cam-slot 226, it has a recess 228 that accommodates a rod-like magnet 238', it has a rearwardly extending pin 232, it has an internally toothed star washer 234 on that pin, and it has an abutment 236 in the form of a pin projecting rearwardly from the rear face thereof. The star washer 234 abuts the rear face of the rod-like magnet and holds it in position within the recess 22S. As indicated particularly by FG. 13, the magnet 239, the pin 232 and the abutment 236 extend rearwardly through the opening 60 in the wail 32. That opening is large enough to permit the lever 222 to rotate from its initial position, shown by FIGS. l and 23, to its lowered position, shown by FIG. 25. The lever 222 differs from the corresponding lever in said co-pending application by having the magnet 234B, by having the pin 232 and by having a deeper cam-slot.

The numeral 238 generally denotes a lever that also is rotatably mounted yon the pivot 62 shown at the lefthand edge of FG. 1. That lever has an opening 24@ which telescopes over the pivot 62, has a cam-slot 242, has an offset ear 244 that extends downwardly below the level of the cam-slot 242, and has two inclined but generally vertically-directed abutments 246 and 248. Those abutments are at the right-hand end of that lever, as that lever is viewed in FIG. 16. When the lever 23S is rotatably mounted on the pivot 62, the ear 244 overlies, and can rest upon, the stud 66, as shown by FIG. 24; but that ear can also be raised up out of engagement with that stud, as shown by FIG. 25. Once the lever 222 has been telescoped over the pivot 62, and once the lever 238 has been telescoped over the pivot 62 and moved into engagement with the hub 224 of lever 222, a C-washer 251) can be set in a groove adjacent the forward end of pivot 62. That C-washer prevents accidental separation of those levers from that pivot. The wall 374 overlies the right-hand end of the lever 233, and thereby keeps the abutments 246 and 248 of that lever in register wth the coin passageway defined by the walls 32 and 374.

The numeral 252 generally denotes an elongated lever which has an upper arm and a lower arm that coact to subtend an obtuse angle. The hub 266 of that lever telescopes over the pivot SS which extends forwardly from the forwardly offset portion 79 of the wall 32. An ear 254 extends rearwardly from the upper portion of the upper arm of lever 252; and that ear extends through the cam-slot 226 of lever 222 and extends into the arcuate slot 76 in wall 32. A pin 256, which preferably is riveted to the upper arm of the lever 252, is located below the level of the ear 254; and that pin extends into the camslot 242 of the lever 238. An opening 258 is provided in the upper arm of the lever 252, and that opening receives one end of a helical extension spring 266. The other end `of that spring is hooked around the stud 81 that extends forwardly from the wall 32 and is immediately adjacent the opening 7S in that wall. A C-washer 268 is set in a groove in stud 81, and that C-washer prevents accidental separation of the spring 266 from that stud; and that spring biases the lever 252 for rotation in the counterclockwise direction. A rearwardly extending offset 262 is provided in the lower arm of the lever 252, and that offset disposes the bottom of that lower arm close to the plane of the forwardly oiset portion 79 of Wall 32. A pin 264 extends forwardly from that rearwardly offset bottom of lever 252, and that pin rotatably supports a roller 265.

The numeral 27@ denotes a latch which has an opening, not shown, at its right-hand end that telescopes over the forwardly extending portion or" the hub 266 of lever 252. That opening is large enough to permit the latch 271i to rotate freely and independently of the lever 252. That latch also has a rearwardly bent portion 271 that defines a concave recess. The latch 270 inclines downwardly and to the left, as it is viewed in FIG. 25; and it has a sharp lower end. Once the opening in the latch 270 has been telescoped over the forwardly extending portion of the hub 260 of lever 252, a C-washer 272 is set in a groove in that forwardly extending portion of that hub to prevent accidental separation of latch 270 from lever 252. Thereupon, a C-washer 274 can be set in a groove in the forward end of the pivot S8, and that C-washer will prevent accidental separation of lever 252 from that pivot. The rearwardly bent portion 271 keeps the rises on the multi-lobe section of the cam from engaging and moving the latch 270.

The numeral 280 denotes the rear section of a cam which is mounted on the output shaft 94 of the mo-tor 9G. That rear section has a rise 282 succeeded by a high dwell 284, it has a low dwell 286 succeeding the high dwell 284, it has a rise 288 succeeded by an intermediate dwell, and it has a further rise 290. The portion of the periphery of the cam section 280, intermediate the rise 29h and the rise 282 constitutes a long, constantradius dwell.

Integrally formed with the rear section 280 of the cam is a hub 302 that extends forwardly from that rear section. Also formed integrally with, and extending forwardly from, that rear section are two pins 296 and a pin 293. Formed integrally with, and projecting radially outwardly from, the rear section 280 yis a circular ange 292. Also formed integrally with, and extending forwardly from, the rear section 280 is a section 294 which has a plurality of notches 295 therein. Those notches accommodate the sharp end of latch 270; and the leading edges of those notches constitute abutments against which the sharp end of latch 270 can bear. The circular flange 292 serves to keep the latch 27() in register with the notches 295 in the notched section 294 of the cam. Four recesses 298 are provided in the front face of the notched section 294; and those recesses are circumferentially spaced. Preferably, the rear section 280, the notched section 294, the flange 292, the hub 302, the pins 296, the pin 293, and the recesses 298 are formed by a die casting operation.

The pins 296 extend into two openings 316 in a multilobe section 324 of the cam, and the forward ends of those pins are riveted :over to permanently secure the multi-lobe section 304 to the rear section and to the notched section. The pin 293 extends through and projects forwardly beyond an opening 315 in the multilobe section 304. That multi-lobe section has an opening at the center thereof which accommodates and telescopes over the hub 302; and it has four circumferentially spaced, tapped openings 31S. Those openings are smaller than, but are in register with, the recesses 29S in the notched section 294. One pair of openings 318 is on one diameter of the multi-lobe section 364, and the other pair of openings 318 is on another diameter of that section.

The multi-lobe section 304 has a rise 306 succeeded by a convex-plano fall, has a rise 398 succeeded by a convexplano fall, has a rise 31@ succeeded by a convex-plano fall, has a rise 312 succeeded by a convex fall, and has a rise 314 succeeded by a convex-plano fall. The rise 306 has a predetermined outer radial dimension, and the outer radial dimension of the rise 368 is less than that predetermined outer radial dimension. The outer radial dimension of the rise 310 is the same as the outer radial dimension of the rise 308. The outer radial dimension of the rise 312 is greater than the outer radial dimenson of the rise 306, and thus is greater than the outer radial dimension of either of the rises 30S and 3119. The rise 314 has the smallest outer radial dimension of all of the rises 306, 308, 310, 312 and 314.

The numeral 320 denotes the front section of the cam,

' and that section has a central opening that telescopes over the hub 302 of the cam. That front section has a rise 322 with an outer radial dimension that is larger than the outer radial dimension of rise 30S or rise 310 but that is smaller than the outer radial dimension of the rise 306;. That front section has two large diameter openl the two large openings in section 326 are set in register with one of the pairs of openings 318, the pin 293 will extend into oneof the openings 325 in thatV front section; and when thoselarge openings are rset in register with the other pair of openings 318, the pin 293 will extend into the other of the openings 325 in that front section. Screws 300 can pass'through the large openings in the front section and seatrin one or the other of the pairs of openings 318 in the multi-lobe section 304, thereby preventing relative rotation between the fronty section 320 and the rest of the cam. When the large openings of the front section 329 are set in register with one of the pairs ,of (openings 31S, the rise 322 on thatifront section is intermediate the rises 306 and 3&2, as show-n by FIGS. l and 24; and at such time the rise 322 is immediately adjacent the rise 314. When those largeopenings in the front section 320 are set in register with the other pair of openings 31S, the rise 322 on that front section is immediately adjacent the rise 366. The threaded Shanks of the screws 360 extend into and are accommodated by the recesses 298 in the notched section 294 of the cam.

The numeral 326 generally denotes a latch which has a sleeve-like huh 327 extending rearwardly therefrom. The opening in that hub telescopes over, and is'rotatably supported by, the pivot 134 carried hy the L-shaped bracket 130. The latchr326 has a notch 328 therein, 1

has a forwardly extending pin 330, has a camming surface 329, has a rearwardly offset ear 332, and has aY forwardly extending pin 334 on that ear. In plan, the latch 326 is somewhat Z-shaped.

A connecting-rod 336 has a slot.338 in the lower portion thereof, has a slot 340 adjacent the bottom thereof, has an opening 342 above the slot 338, land has an opening 343 at the top thereof. Theslot 340 telescopes over the pin 334 onthe ear 332 of latch 326; and a helical extension spring y344 has the lower end thereof set in a peripheral grooveV in the forward end of the pin 334.

The Vupper end ofthe spring 344 is hooked in the opening Y hand edge of the opening 64 to limit clockwise rotationV of the coin-responsive element 348. The coin-responsive element has a coin-holding portion 358 and has a coin` feeling portion '360 located above the level of the coinholding portion 358. The'coin-responsive element 348 Yalso has a surface 359 thereon, adjacent the upper left- `hand edge thereof, that selectively approaches the abutments 246Vand 248 on the lever 238. A- C-washer, not shown, will fitin` the groove 353V in the pin 352 to prevent accidental separation of the connecting rod 336 from that pin 352, and thus from the coin-responsive element 343. That coin-responsive element is similar to the corresponding coin-responsive element in said co-pending application, but the coin-feeling portion 360 rinclines to the lett rather than to the right on Ythatrcoin-responsive element.

The numeral 364 AgenerallyY denotesia second coin- L ,responsive element; and that coin-responsive element has,

an opening 366 which telescopes over the pivot 52 to ,Y

cause the coin-responsive elements 348 `and 364 to rotate .concentrically A slot 368 is provided in the coin-responsive element 364, andthat slot telescopes over the'pin 354 which extends forwardly from the coin-responsive element 343. An opening 367 is also provided in the coin-responsive element 364, and that opening Atelescopes over the pin 352 carried by the coin-responsive element 348. The pins 352 and 354 coact with opening 367 and slot 36S to cause` a passageway for a quarter. The inlet of that passageway Y will he below and in register with the quarter'outlct of the slug rejector, and the outlet of that passageway will he above and in register with the inclined portion of the accepted coin chute 42. That passageway will force each accepted quarter to engage the switch actuators 11@ and 192 of the switches 136 and 96, respectivelygrand as that v quarter engages andl moves past Vthose switch actuators, that quarter will cause those actuatorstoshift the'contacts of those switches from normal position to actuated position and then freethose contacts for return Yto normal position.

- The partition or wall 374 has'an upper arcuate slot 372 which accommodates the transversely-directed, coinreceiving portion of the switch arm 110; and it has a lower of connecting rod 336, and the other end of that spring is hooked in an opening in the plate 68 on wall 32. The n,

spring346 biases the connecting'rod 336 upwardly, and

. therebyY biases the latch 326 for rotation ins-the clockwise direction. The'connecting rod 336 diters from the correspondingV connecting rod in said co-pending application by having theslot 340 and the spring 344 which provide a lost-motion connection between latchV 326 and cony neet-ing rod 336.

That pin telescopes through the opening 343 at the top of the connecting rod V336 `and t'.h=,reby interconnects 'that connecting rod and that coin-'responsive element. A rvpin 354 alsoprojects forwardly from the coin-responsive element 348, and a pin 356 projects rearwardly from that element. The pin 356 extends through the opening'64 which is in the wall 32 and which is disposed above and to the left of the pivot 52; and that -pin engages the rightarcuate slot 373 which accommodates the transverselydirected, coin-receiving portion of the switch arm 102.

That partition or wall also hasV an arcuate notch 375 which accommodates the forwardly extending `pin 354 on theV coin-responsive element 348. Further, the wall 374 has three projections377 at itsrright-handv edge; and those projections extend through three openings in the flange 38. The interaction between the projections 377 and those openings in the iange 38 fixedly holds 4the right-hand edge of the wall 374 relative to therframe 30.

The numeral 376 denotes a partition or wall which is disposed to the left of the Wall374 in FIG. V3; and the wall 376 has a number of bosses which exten-dto the rightV in FIG. 3 and abut the left-handfaec of the wall'374; and those bosses are shown by crossk hatching in FIGS. 23-25. The numeral 373 -denotes an inclined upper face on the inclined surface 378, and the numeral 382`denotes a second concave surfaceY onV that boss which coacts with Vthe concave surface 389 to define a cusp. A third concave surface 384 is provided on that boss, and it forms an almost imperceptible cusp Ywiththe concave surface 332.`

An inclined surface 386 on that boss coacts with the concave surface 384 to define a cusp-like projection; and

a vertical surface on that boss extends downwardly from the inclined surface 386. A reversely inclined surface 390 is provided at the bottom of the vertical surface 386. A reversely inclined surface 390 is provided at the bottom of the vertical surface 388, and a second vertical surface 392 extends downwardly from the inclined surface 390. Another boss at the rear surface of the wall 376 has a concave face 394 adjacent the rtop thereof, has a second concave face 396 which coacts with the first concave surface 394 to form an almost imperceptible cusp, has a third concave surface 398 that coacts with the concave surface 396 to form a more perceptible cusp, and has a concave surface 400 that coacts with the concave surface 39S to perform a very perceptible cusp. A vertical surface 402 extends downwardly below the level of the concave surface 400, and that vertical surface terminates at a point yabove the level of the top of the coin-responsive element 364. The third boss at the rear face of the wall 376 is denoted by -the numeral 404, and it is shown particularly by FIGS. 24 and 25. That boss is horizontally directed, and it has an opening through it which accommodates a fastener 406. The wall 376 has two arcuate slots, not shown, that are identical to and are in register with the arcuate slots 372 and 373 in the wall 374.

The wall 376 and the two vertically directed bosses thereon coact with the wall 374 to define a passageway for dimes; and the inlet of that passageway is below and in register with the dime outlet of the slug rejector, and the outlet of that passageway is above and in register with the inclined portion of accepted coin chute 42. An accepted dime entering that passageway will be forced to move past the two arcuate slots and to move the switch arms 110 and 102 downwardly. In so moving those switch arms, that dime will cause the contacts of the switches 106 and 96 to shift from their normal position to actuated position; and as that dime passes out of engagement with the switch arms 110 and 102, those switch arms will be freed for movement toward normal position. 40

The wall 376 coacts with a paration or wall 416 to define a pasageway for nickels. The walls 374, 376 and 416 are substantially identical to the coresponding walls in said co-pending application, and they perform the same functions. 4

The left-hand edges of the walls 416 and 376 are held rigid relative to the wall 32 of frame 30 by screws 418 and 406, shown in FIG. 1. Further, the right-hand edge of the wall 416 is held fixed relative to the frame 30 by three projections 408 which seat in three vertically alined openings in the flange 38.

The numeral 410 generally denotes a strip of metal that constitutes a liner for the inclined front portion of the accepted coin chute 42; and that strip of metal also xes the forwardmost vertical wall of that chute. The upper end of the metal strip 410 is provided with twoears 409 which are bent forwardly and downwardly to have a configuration comparable to the uppermost edge of the inclined portion of the coin chute 42, as shown particularly by FIG. 3. Those ears extend far enough to underlie part of the front face of the inclined portion of the accepted coin chute 42, `and hence they serve to anchor the upper end of the metal strip 410 relative to the coin chute 42.

The metal strip 410 has an angle approximately one hundred and thirty five degrees in it at a point below the lowermost part of the inclined portion of accepted coin chute 42. That metal strip also has a right angle bend at the level of the bottom sunface of bottom wall 140; andthe bottom 411 of the metal strip 410 extends forwardly from that right angle bend. A slot, not shown, is provided in the bottom 411, `and one of the screws 220 extends upwardly through the said slot and has its head underlying those portions of the bottom 411 which define that slot. Consequently, that screw ixedly secures 412, and that ange has a slot therein which acco-m-l modates the shank lof another of the screws 220. As a result, the head ott that other screw underlies 'those portions of the flange 412 which define the notch and thereby clamp that flange tightly against the bottom wall 140 of the change-making device.

The numeral 420 denotes a coin guide that is held forY rotation adjacent the top of `the coin reservoir 214 by the screw 424; and that screw also holds one side of the v coin inlet 422 for the coin yreservoir 214. The other end of that coin inlet is held by the screw 426. Nickels leaving the passageway defined by the walls 416 and 376 pass between the two upstanding ears of the coin guide 420 and move downwardly through the coin inlet 422 to enter 4the coin reservoir 214.

Normal Position of Components The normal position of the components of the changemaking device provided by lthe present invention is indicated by FIG. 1; and, in that position, the coin-responsive elements 348 and 364 intercept quarters and dimes respectively. Also, in that position, the rear section 280 of `the cam has its low dwell 286 adjacent the roller 265 on the lower yarm of lever 252. Further, in that position, the rise 322 on the front section 320 of rthe cam is engaging the roller 188 carried by the pin 186 of the payout slide, yand that rise is coacting with the convex fall succeeding the rise 312 to hold that slide with its coinreceiving openings 192 below and in register with the outlet of the coin reservoir 214. Additionally, in that position, the pin 182 held by the ears 180 on payout slide 174 are in engagement with the camming surface 329 on the latch 326, and that pin is holding the notch 328 on that latch up and out of register with the pin 182. Moreover, in that position, the switch arms and 102 are 5 adjacent the upper ends of the arcuate slots 372 and 373,

respectively. Furthermore, the lever 222 has its abutment 236 above and out of engagement with the switch arm 102, and the lever 238 has its ear 244 lresting upon the stud 66.

If an adequate supply of nickels is in the coin reservoir 214, those nickels will be holding the feeler 118 against full entry into the slot 215 at the rear of coin reservoir 214. This enables the switch 116`to energize a lamp in the vending machine which is associated with a sign indicating that nickels, dimes and quarters can be accepted. That lamp will rem-ain illumina-ted as long tas the numlber of nickels in the reservoir 214 is suicient to block full entry of the feeler 118 into the coin reservoir 214 through the slot 215; land the feeler 118 is made short enough to require -at least four nickels to be in the reservoir 214. In actual practice, the feeler 118 is made short enough to require more than seven nickels to be in the reservoir 214 to .prevent full entry of the [feeler 118. When the supply of nickels in the reservoir 214 falls below the prescribed number, the feeler 118 will move inwardly through the slot 215 in thatreservoir and cause the switch 116 to deenergize the first said lamp and to energize a 4lamp adjacent a sign indicating that coinage equalling the sales price must be inserted. The feeler 1x18 and the -switch 116 perform the functions which the corresponding feeler and switch perform in the said co- -pending application. Throughout the rest Yof this description it will be assumed that suicient nickels are in the coin reservoir 214 to hold the feeler 118 against full entry through the slot 215.

nickel will' continue-on to the bottom'of that passageway. `It' the reservoir 214Vv is'nort full,A that nickel will enter,

and'come to rest in, that reservoir. However, if the reservoir' ifs full, that nickel willy engage va nickel held by the guide 420iandbe deected tothe right where itwill then fall `downwardly into the accepted coin chuteV 42." A suitable conduit, vnot shown, willl extend between the lzvotto'mY of the accepted coinV chute and the cash box. ott

` Ast'he switcharm'- 11'0'iwa's moved downwardlyby the' nickel, it caused the switch 1106 to sendvfan impulse tothe That impulse will start Ithe' vendingV vending -machine vcycle of they vending machine,.and .the electrical*circuitv of pass through one complete cycle. Thehniclkel did not move the switch -arm 2vbecause that arm `does not ex# tend into the passagewaydened by the walls 416 and 376.

' i Dil-1re Operation lf aV dirne is introduced into they c oin- Vslot of the vend.l

ing'machine, that dime will-pass through .the slug rejec-v `tor and Aenterl and move downwardly through the passage- 'way'denedby-the walls 374 and 376.VV In moving downwardly through that passageway, that dime will be deflected to the left bythe concave surface 380 andvforce the 'switch 110 to move downwardly toward the lower end of the slot 372; thereby sending an impulse to the vending machine to cause'that vending machine. to start itscycle of operation. zThe arcuate surface 394 pen thisleft-hand movement of the dime; and the arcuate surfaces 396 and 398 start that dime moving back toward the right( The arcuate surface 382 accommodates this night-hand movement of. the dime; iandthe yarcuate sur- 'face1384,then,starts that dime moving back to the-left. That dimewill thus be caused to engage the switch arm 102' andk move that switch armdownwardly toward the lower end of the'arcuate-slotr 373.-r As the switch arm 102approaches the lower end of the arcuate slot 373, it will be attractedrto4 and Vheldby themagnet 230 on the lever 222. When the switch arm 102 is so attracted and held, it is below .outof engagement with the dirne, f

.which has meanwhile4 comeV to rest on Vthe upperface of the coinfresponsive element 364, as shown particularlyv by FIG. 23.

Hence,even though-the dime is out vof en- Y the abutment 24S on lever 233. That engagement prevents further counter clockwise rotation of the coin-responsive elements 348 and .364, but that rotation has been Y great Venough to` permit the dime to move downwardly into engagement with the coin-feeling andV coin-holding n surface37 on-the coin-responsive elements 364.

Also-beforetherise 322 moves out of engagement with Y the roller 18S, that rise will have caused fur-ther counter i clockwise rotation of the latch 326.` Such rotationican "i the vending'm-achirie will causefthatrvending machine to Y gage'rnent with the switch arm, 102,'th-at `switch ar-mis held in switch-actuating position kandaotulates the switch 96. Y The actuation of switchr 96energizes'the motor 90, and that motor rotates the outputslraft 94 in the` counter clockwise direction, as that sli-att is viewedvin FIGS. l mazo-25., l Y I j hat counter clockwise rotation of. that shaftl enables therise 322 onV Vthe front section`--r32 Vof the cam to act Y' throughthe roller 18S,Y thefpin.y 186 and the ears '184 to move the payout slide 174 tothe right; and such movement kacts through the camming surface 329 to r0-V tate the latch 32,6 in the counter clockwise direction. v That counter clockwise rotation of latchV 326 acts through the pin- 334, and the springA 344VV to pull downwardly on the vconnecting` rodl 336 and thereby rotate the coinexperienced at this time.

not rotate the coin-responsive elements348 and 364 further in the counter clockwise direction because of the engagement of surface 359 on coin-responsive element 343;.with the vabutment 24S Aonlever 23d,..and hence that further counter clockwise rotation of thelatch 326 mere-` ly stretches the spring 344. The slot 346 in the connecting Vrod 336; accommodates that further counter clock-l wise rotation oi' the latch 326 Vby enabling the Vpin 33.4 to move` downwardly relative to the connecting rod 336.

Thaty further movement of the'latch 326 will be very limited, and hence the consequent downward movement' f ofthe. pin 334 will be amply accommodated by the slot 340 in connecting rod 336.

As the .rise 322 moves past and out of engagement with the roller 188 on pin 136, that Vroller will engage the convex part of the convex-planofall' which succeeds Y that rise; and that-convex part will permit the slide 174 to start moving to the left. lThat movement of the Slide 174 will enablel the cam surface 329 on latch 326 to respond to the forces of spring 346 and 344 to move downt wardly relative-to the pin 182'carriedrby thejears 180l on slide 174. The resulting clockwise rotationof-the latch 326 will Vfree the coin-responsive elements 348 and- 364 for rotation in the clockwise direction under the action offspring 346; but the'dime', in the passageway defined by the' walls 374 and 376, will be intermidiate thercoin-fee'ling. and coin-holding surface 370' of coinr'e'sponsive' element 364 and the vertical surface 3880i the boss on wall 376. Consequently, little or no clock-V wise rotation of` the coin-responsive elements will bef As a result, the latch 326 will' be held in' the position indicated by dotted lines` inFIG.V

V24; and, .in'that position, the'notch" *323V ori-that latch is I.

above the level of, and out of register 'vi/ith,y the` pin 182 carried by the ears 180 on' slide 174; Thereafter',l 1 V,when the further counter clockwise'rotation of the shaft 94 moves 'the plane part of thev convex-plano fall on the front section`32`0 of the cam adjacent the roller 188V carried by the pin 186, the slide 174 will respond to the 'i forces of springs 216 toV pull the'slide Vfrom coinsloading j Vposition to coin-discharging position.

sition, the opening 192 of the slide 174 is in register with the discharge opening 1420i the bottom wall 140; and

.the nickel in the opening 192 of the slide 174 will fall Vdownwardly through vthe discharge opening 142. That nickel will pass Vintoa conduit, not shown, which will lead to a coin cup at the exterior of the vending machine;

and it can then be removed'from that cup by the pa-V tron. ,l That nickel willy be urged downwardly and out ofthe opening 192 in the slide 174 and downwardly and out of the opening 142 by the inclindedgrght-hand side of 'the projection 207 intermediate the ends of spring 206. The limit of the left-hand movement'of the slide j 174 Vis determined by the engagement of the vleft-hand responsive elements 34S and364A in the counter clockwise direction. Before the rise 322 onthe front section 320 Vo-the vcarn'moves out of engagement with the roller 1,88 Vcarried byjthe pinA 186, that rise will have acted through the slide 174y and the latch 326.1:0 rotate the coinyresponsive elements 348 and 364 farienough in the counter clockwiset direction to move the surface359 on coinresponsive element 348 into abutting engagement with end of that slide with vthe resilient padr168. The dis` charge nickell is, of course, required change where a dime is inserted and the sales price is ve cents.

Almost simultaneously with the freeing of slideY 174 for movement to coinfdischarging position, the rise 288 on the rear section 2813. of the cam engages the roller 265 carried by the pin 264 on the lowerl arm of lever V252. That rise responds to further counter clockwise rotation of the. shaft 94 to rotate the lever 252 in the clockwise direction, and that rotation ofy lever 2,752 moves theear 254 to the right inthe camfslotV 226. Therotation ofthe lever 252'by the rise 288 is not extensive,

In the latter' poprior to the time the rise 36d on the multi-lobe section 3124 of the cam engages the roller 188; but that rotation is great enough to move the ear d out of engagement with the left-hand end of the cam-slot 226; and, therefore, the lever 222 is freed for rotation, under the action of gravity, downwardly toward the stud 58. However, the flux lines from the magnet 230 are strong enough to enable that magnet to hold itself in engagement with the switch arm 102, which is adjacent the lower end of the arcuate slot 373; and this means that the lever 222 will remain in an intermediate position close to its initial, raised position. As a result, at the time the rise 386 engages the roller 188, the lever 222 has rotated only a short distance downwardly from its initial, raised position. i

Further counter clockwise rotation of the shaft 94 causes the rise 386 to move the `slide 174 to the right, and causes the rise 288 to rotate the lever 252 far enough in the clockwise direction to move the ear 254 into `engagement with the convex portion of the cam-slot 226 in lever 222; and the engagement of that ear with that convex portion forces the lever 222 to rotate far enough in the clockwise direction to produce an air gap between the magnet 239 and the switch arm 102. Thereupon, the lever 222 will drop downwardly to the position shown by FIG. 25; and in that position that lever rests upon the stud 58. rl`he lever 222 will drop downwardly very rapidly, and the abutment 236 thereon will engage and hold down the arm 102 of the switch 9o, thereby keeping that switch arm from returning to switch-restoring position. The downward movement of the lever 226 is so rapid that the motor 99 operates as though the switch arm 102 did not move upwardly at all.

The movement of the slide 174 to the right by the rise 306 moves the coin-receiving opening 192 toward the coin reservoir 314, but before that opening has been placed in register with the coin reservoir 21d to receive another coin, a notch 295 of the notched section 294 of the cam has moved under the pointed end 269 of the latch 271i. Thereupon, reverse rotation of the cam is prevented even if someone were to shut ofi the power by ulling the vending machines plug out of the wall socket. Hence, even if someone deliberately removed the vending machines plug from the wall socket to remove the electromotive force from the shaft 94 and to enable the springs 216 to cause the slide 274 and the pin 186 thereon to start the cam rotating in the reverse direction, that reverse direction could not be hurtful. Any such reverse rotation prior to the time the said notch 295 passes under the sharp end of latch 270 can not be hurtful because the slide 174 will not have been moved far enough to the right to receive a nickel from the coin reservoir 214- and the movement of the empty slide to coin-discharging position can neither pay out an extra nickel nor move the slide out of register with rise 366; and any such reverse rotation after the notch passes under the sharp end of latch 270 can not be hurtful because it is stopped before the slide can reach coin-discharging position. As a result the removal and the re-insertion of the vending machines plug will merely delay and can not cheat the operation of the change-making device.

Before the rise 386 on the multi-lobe section 394 of the cam can move the slide 174;l far enough to the right to cause the pin 182 to engage the latch S26-held in the dotted line position of FIG. 24 by the engagement of coin-feeling portion 370 of coin-responsive element 364 with the dime-the rise 29d on the rear section 288 of the cam engages the roller 265 on the lower arm of lever 252 and rotates that lever further in the clockwise direction. That further rotation of lever 252 moves the pin 256 on the upper arm of lever 252 into engagement with the inclined surface at the right-hand side or" the Camelot 242 of lever 238 and starts rotating thatlever in the counter clockwise direction. About the time the rise 386 has moved the slide 17d far enough to the right to move the pin 182 into engagement with the camming surface 329. on the raised latch 326, the rise 291B has enabled the pin 256 to rotate lever 238 far enough in the counter clockwise direction to raise the abutment 248 upwardly and out of register with the surrace 359 on the coin-responsive element 348. At such time, the abutment 246 on the lever 238 is in register with the surface 359 on the coinresponsive element 348.

Continued counter clockwise rotation of the shaft M- enables the rise 396 to move the slide 174 far enough to the right to enable the pin 182 to rotate the latch 326 further in the counter clockwise direction to the position shown by FIG. 25. At this time, the pin 334 has moved far enough downwardly to act through the spring 344 to place the surface 359 of coin-responsive element 348 in engagement with the abutment 246 on lever 238; and, in fact, that pin can move downwardly and out of engagement with the upper end of the slot 340. In moving upwardly from its initial position where its abutment 248 limits the counter clockwise rotation of the coin-responsive elements to the intermediate position of FIG. 25 where its abutment 245 limits the counter clockwise rotation of the coin-responsive elements, the lever 238 permitted the coin-responsive element 364 to move far enough in the counter clockwise direction to enable the dime to fall downwardly past the coin-holding and coinfeeling surface 378 and to move to the accepted coin chute 42. The gauging action of the lever 238 plus the overtravel of latch 326, made possible by the lost-motion connection between that latch and connecting rod 336, makes certain that while the coin-responsive elements 348 and 361?r move far enough in the counter clockwise direction to enable dimes and quarters to move successively downwardly to coin-feeling and coin-freeing positions, those coin-responsive elements can not move so far in the counter clockwise direction that dimes and quarters are released prematurely.

After the dime has moved downwardly past the coinfeeling and coin-holding surface `376) on coin-responsive element 364, the further counter clockwise rotation of the shaft 94 moves the rise 306 beyond and out of engagement with the roller 188; and thereafter the convex part of the convex-plano fall succeeding that rise will let the latch 326 rotate in the clockwise direction. That rotation places the notch 328 in the path of the pin 182; and although the plane part of that convex-plano fall frees the slide 174 for movement toward coin-discharging position, the notch 328 on latch 326 prevents such movement. Hence, further counter clockwise rotation of the shaft 94 will not permit further nickels to be paid out.

During the subsequent, continued counter clockwise rotation of shaft 94, and prior to the time the rise 308 on the fourlobe section 304 of the cam moves into er1- gagement with the roller 188 on the slide 174-which roller is held adjacent the position of FIG. l-a second notch 295 in the notched section 294 of the cam will pass under the sharp end 259 of latch 270. The inter action of that second notch 295 and the pointed end 269 of latch 270 is not significant during the dirne operation of the change-making device because the slide 174 is already solidly latched against movement to coin-discharging position by the engagement of the notch 328 of'latch 326 with the pin 182 of the slide. However, the interaction of that second notch 295 and the pointed end 269 of lever 271B is significant in the quarter operation of the change-making device, as is brought out hereinafter.

The rise 388 will act through the roller 188 on the pin 186 to move the slide 174 far enough to the right to rotate the latch 326 to slide-freeing position. However, further counter clockwise rotation of the shaft 94 will not lead to the paying out of another nickel because the coinresponsive elements 348 and 364 are not held in their left-hand positions by coins and, therefore, are free to rotate to their right-hand positions and permit the notch 328 `on the latch 326 to move into the patch of, and to 4great Yas that of rise 322 or rise Sii-6, the coin-responsive elements 348 and 364 are not rotated as far in the counter clockwise direction as they were rotated when rise 322 or rise 366 engaged the rollerlSS. However, the rise 36S I did move the roller 18S far enough to cause the slide 17d to rotate theplatch 326 to slide-freeing position.

. Further Vcounter clockwise rotation of the shaft 94 moves j the rise 310 on the four-lobed section 304 of the cam into Y engagement with the roller 135 on the slide 174. Shortly I before that rise engages that roller, which roller is adjacent the position shown by FG. 1, a third notch 295 of the notched section 294 of the cam passes under and engages the sharp end 269 of the camft).y As was the case with vthe second notch 295 of the vnotched section 2794, the interaction of the third notch 295 with the pointe end 269 of latch 271i is not significant in the dime operation of .the change-making machine. However, .the interactionk of that third notch 225 with vthe sharp end 269 of latch 270 is significant inthe quarter operation or" the change-making machine, as is explained hereinafter. Continued counter clockwise rotation of theshatt V94 will envrisel() passes out of engagement with the roller 188.

The rise 310, like, rthe rise 30S, has a yshorter outer radial dimension than rise 322 or rise 3%; and hence, the rise 310,; will not rotate the coin-responsive elements 343` and 364 as far in the counter clockwise direction. However, the/,rise 31) will rotate'the latch 326 to slide-freeing position.

Furtherv counter clockwise rotation of the shaft 94 moves the rise 312 on the four-lobe section 304 of the cam toward the roller 18S and moves the rise 282 on the` rear section 280 of the cam toward the. roller 265 at the lower end of the lower arm of the lever 252. That latter rise then rotates the lever 252 still further in the clockwise direction and ,moves the pin 256cm the upper arm of ,lever 252 adjacentfthe right-hand endl of the cam-slot 242 of lever 238. Such movement of the pin 256 raises K Vthe, leverr238 toits vfully raised position, and in that position, the lever 23S has its abutment above the level of theV top of coin-responsive element 348. Further counter clockwise rotation of the shaft'94 moves the rise 282 out of engagement with theroller 265 on the lower arm of the lever 252, but the high dwell 28,4 on the rear section' 280 of thecam holds the lever l252 in its full clockwise position, and thereby holds the lever 238 in its fully raised position. A concave notch can be provided to the left ofthe abutment 24S on lever 238, asy shown by FIGS. 16,

to. permit thelever 238 to move to fully raised position without engaging and slightly raising the lever-222. However, such a notch is not necessary because the small rais-V ing ofthe lever.222, by an uri-notched lever 238, could notv movethe abutment 236 on lever 222 farenough upwardlyfto permit the.V switch arm 102 to move into Y switch-restoring position. Y

y After the rise 282 has moved thelever252 to its full clockwise position, the fourth notch 295 of the notched section 294 will move under the sharp end 269 of the latch 270. and third notches 295 under the sharp end 269 of the latch 270, the movement of the fourth notch y295 under v the pointed end 269 of latch 276 is not significant in the dime operation but is significant in the quarter operation,

' as is explained hereinafter. f Further counter clockwise rotation of the shaft 94` will move the rise 312 on the multi-lobe section 304 into' As in the case of the movementy of the secondY von the slide.

as f v engagement with lthe roller" 188 on the slide 174i;k and that rise will act ,through roller 158 and pin 182 on the slide 174 to rotate the latch 324 far enough to rotate the coin-responsive element 348 to its fully counter clockwise position. In moving to that position, the coin-responsive element 34S moves the surface 359 thereon below and to the left of the abutment 246 on lever 238. This movement of vthe coin-responsive element 348v is not signicant in the dirne operation of the change-making rdevice but it is signicant in the quarter operation of that device, as is explained hereinafter. During that movement of the coin-responsive element 34S, the high dwell 284 on the rear section 28h of the cam continued to hold As the rise 312 moves beyond the roller `188, the slide 174 starts to move to thef left, but it is quickly heldy .against movement to coin-discharging position by the'engagement of the notch 328 of latch 326 with the pin 182 y Before vthat engagement occurs, the high dwell 284 on the rear section 28) moves out of engagement with the roller 265 on the lower armof lever 252; and thereuponthe spring 266 starts rotating the lever 252 i in the counter clockwise direction. That rotationrmoves the pin 256 on lever 252 to the left in the cam-slot 242 of lever 238v and permits that lever to start rotating in the clockwise direction; and before the shaft 94 has rotated far enough in the counter clockwise direction to move the rise 322 on the front section 320 of the cam into engagement with the rollerY 188 of the slide 174, the

spring 266 will have pulled the lever-252 to the position shown by FIG. 1. 252 places its ear 254 Vadjacent the left-hand end of the cam-slot 226 of lever 222V and thereby forces that lever to rotate to the raised-position shown by FIG. 1. Also,

Vthe pin 256 on the lever 252-moves adjacent the lef-thand end of the cam-slot 242 of the lever 238, thereby enabling that lever to rotate downwardly until its ear 244 rests upon and is held by theV stud 66 on Vthe wall`32. As the lever 222 is raised to its upper position, it permits the n spring within the switch 96 to return the switch arm 102 to the upper end of the arcuate slot 373; and thereupon the contacts of that switch return to normal position and f de-energize the motor 9h. However, the slide 174 did not stopV moving to the left; instead, that slide responded v to the pull of the springs 216 to move to the left until the roller 13S engaged the rise 322 on the front section i 320 of the cam and rotated that cam far enough in the reverse direction to bring the convex fall, succeeding the rise 312 into engagement with the roller 188. Atr such time, the components of the'V change-making device are- Y' again in the normal position, indicated by' FIG. 1.

was discharged bythe payout slide 174.

each of theV rises 322, 306, 3%, 310i andr312- during the dime operation of the change-making device, but onlyl Vthe rise 322'enable'd the slide to move to coin-discllargingl position. When the rises 366, 398, 31@ and'312 caused the slide 174 to move the latch 326 to slide-freeing position, no coin held the coin-responsive elementsy in Ytheirv left-hand positions and hence those coin-responsive elements ywere free to move to their right-hand positions and permit the latch 326 to move into siide-latching position.

Quarter Operation f 'I If a quarter isr inserted in the coin 'slot of the vending machine, that quarter will pass through the `slug rejector and be delivered to the passageway defined by the wall 32 and the wall 374. The boss 31'will direct that quarter to the left and cause it 4to'engage the switch'arm 110 and move that switch farm downwardly, Ytherebyrenabling the switch 106 to send an impulse to the vending machine.

In moving to that position, the lever Y aisance The boss 37 will force the quarter to move back to the right, and then the boss 33 will force the quarter to move to the left once again; and, in so moving, the quarter will engage the switch wire 192 and move it downwardly toward the bottom of arcuate slot 373. As the switch arm 162 approaches the lower end of the slot 373, it will be attracted to the magnet 230 and will be pulled downwardly and away from the quarter, which will come to rest on the top of the coin-responsive element 34S, as indicated by FIG. 23.

The downward movement of the switch arm 102 will, as in the dime operation, energize the motor 90; and that motor will start the shaft 94 rotating in the counter clockwise direction. The rise 322 on the front section 326 of the cam will move the roller 138 to the right and thereby cause the slide 174 to rotate the latch 326 to slide-freeing position. As the latch 326 so rotates, it will act through the spring 3634 and the connecting rod 336 to rotate the coin-responsive element 348 in the counter clockwise direction until the surface 359 on that coinresponsive element engages and is held by the abutment 243 on lever 238, as shown by FIG. 24. At this time, the quarter will be able to move downwardly until it is held by the coin-holding surface 358 on the coin-responsive element 348. As the rise 322 on the front section 326 of the cam continues to move the roller 188 to the right, the latch 326 will be rotated still further in the counter clockwise direction; and the slot 340 and the spring 344 will accommodate that additional rotation.

Further counter clockwise rotation of the shaft 94 moves the rise 322 out of engagement with the roller 188 and permits the roller 18S to engage the convex part of the convex-plano fall that succeeds the rise 322; and thereupon the slide 174 is free to start moving to coindischarging position, because the quarter is holding the latch 326 in raised position. The continued counter clockwise rotation of the shaft 94 moves the plane part of the convex-plano fall, succeeding the rise 322, adjacent the roller 183; and thereupon the slide 174 moves to coindischarging position and pays out one nickel.

Almost simultaneously with the freeing of slide 174 for coin-discharging movement, the rise 28S on the rear section 23% of the cam starts rotating the lever 252 in the clockwise direction; and that rotation enables the lever 222 to start rotating downwardly. However, as described in connection with the dime operation, the magnetic ux lines from the magnet 230 hold the lever 222 in an intermediate raised position.

Further counter clockwise rotation of the shaft 94 enables the rise 306 to engage the roller 188 and move the slide 174 to the right, and enables the rise 23S to move the lever 252 further in the clockwise direction. That further rotation of lever 252 causes the ear 254 thereon to engage the convex portion of the cam-slot 226 and force the lever 222 to rotate downwardly. Once this further clockwise rotation of lever 222 creates an air gap between magnet 23) and switch arm M12, the lever 222 quickly falis all the way down to the position shown by FIG. 25. As in the case of the dime operation, the downward movement of the lever 222 is so rapid that the switch arm 1132 does not have a chance to move upwardly to stop the motor 90.

Before the rise 3516 has moved the slide 174 far enough to the right to place the coin-receiving opening 192 in register with the coin reservoir 214, the first notch 295 of the notched section 29d moves into engagement with the shmp end 269 of latch 279. That engagement prevents undue reverse rotation of the cam, all as explained above.

Before the rise 366 can move the side 174 far enough to the right to cause pin 182 to engage the raised latch 326, the rise 29@ on the rear section 236 of the cam moves into engagement with the roller 265 on the lower arm of lever 252 and rotates that lever still further in the clockwise direction. That rotation moves the pin 256 against the inclined surface at the right-hand side of the cam-slot 242, thereby rotating the lever 23S in the counter clockwise direction and raising the abutment 243 upwardly and out of the path of the surface 359 on coin-responsive element 346. At such time, the abutment 2% is in register with the surface 359 of coin-responsive element 3413. Consequently, when the rise 306 causes the latch 326 to rotate the coin-responsive element 348 in the counter clockwise direction, the surface 359 on that coin-responsive element can, and does, move adjacent the abutment 246 on the lever 238. Such movement of the coin-responsive element 348 is not signifierait in the quarter operation of the change-making device, but it was signiicant in the dime operation of that device because'it enabled the dime to move downwardly past the coin-feeling and coin-holding surface 376 on the coin-responsive element 364.

Continued counter clockwise rotation of the shaft 94 moves the rise 3% past and out of engagement with the roller 183 on the slide 174; and it subsequently moves 1 the plane part of the convex-plano fall, succeeding the rise 3116, adjacent the roller 13. At this time, the latch 32e is held in slide-freeing position by the engagement of the coin-feeling surface 3u@ on the coin-responsive e-lement 348 with the quarter; and, consequently, the slide 17d again moves to its coin-discharging position and pays out a second nickel.

Further counter clockwise rotation of the shaft 94 moves the rise 398 into engagement with the roller 188, and starts the slide 174 moving toward coin-loading position. Before that slide can reach coin-loading position, the second notch 295 of the notched section 294 of the cam moves under the sharp end 269 of the latch 270; and this means that after the slide 174 has been moved to coin-'loading position but before the rise 3115? and the convex part of the convex-plano fall therebehind have moved out of engagement with the roller 188, any deenergization of the motor will not lead to the paying out of an eXtra nickel.

Continued counter clockwise rotation of the shaft 94 enables the rise 3118 to move the slide 174 to a position where it could move the latch 32d to slide-freeing position; but that latch is already in slide-freeing position because the quarter is being held and felt by the coin-responsive element 34S. Consequently, when the rise 303 and the convex part of the convex-plano fall therebehind move beyond the roller 188, the slide 174 will be able to move to the left-hand end of its path of reciprocation and pay out a third nickel.

Further `counter clockwise rotation of the shaft 94 will move the rise 31% into engagement with the roller-188 on the slide 17d, and start that slide moving to the right. Before that slide can move its opening 192 into register with the coin reservoir 214, the third notch 295 of the notched section 294 of the cam will move under the sharp end 269 of latch 27d. This means that after the slide 17 4 has moved far enough to pick up a fourth nickel, the de-energization of the mot-or 9@ can not lead to the paying out of an extra nickel.

Continued counter clockwise rotation of the shaft 94 will enable the rise 310 to move the slide to a position where it could movethe latch 326 to slide-freeing position. However, that latch is already in slide-freeing position .because the quarter is being held and felt by the coin-responsive element 348. Consequently, when the rise 319 and the convex part of the convex-plano fall therebehind move out of engagement with the roller 188 on the slide 174, that slide will move to the left-hand end of its path of reciprocation and pay out a fourth nickel.

Continued counter clockwise rotation of the shaft 94 moves the rise 312 into engagement with the roller 188 on the slide 174 and starts that slide moving to the right. Shortly after the rise 312 engages the roller 188, the rise 282 on the rear section 231) of the cam engages the roller 265 on the lower arm of lever 252 and starts that lever ymoving further in the clockwise direction. yther rotation of lever 252 moves the pin 256 toward the to its full counter clockwise position.

aleaeeo That furright-hand end of the cam-slot 24%2 in the lever 233 and raises the abutmentf246 of the lever upwardly out of fourth notch 29S of. the notched. portion 294i makes sure that the (le-energ'zation of the motor 9i) will not givey a patron an extra nickel.

Continued counter clockwise rotation oi' the shaft. 94 enables the pinlZ on the slideV E74 to rotate the latch 326 far enough to rotate the coin-responsive element 343 lln that position, the surface 359 on that coin-responsive element has l' moved to the left of the abutment246 on the lever 238,

land the coin-holding surface 358 has moved out of engagement with the quarter; and thereupon the quarter falls downwardly to the accepted coin chute d2.V v Continued counter clockwise rotation of the shaft 94 moves the rise l'beyond the roller SS on slide 174,

' and also moves the high dwell Zad out of engagement Y of the high dwell 28d out ofcngagement with the roller 265 enables the spring 266 to rotate the lever 252 in the counter clockwise direction and force the lever 222 to rotate upwardly to its normal raised position while permitting the lever 23S to rotate downwardly to its normal lower position. At such time, the components of the change-making device are kagain in the position shown by S22, will be engaging the roller 188 on the'slide 174 in the normalV position of the change-making device. Also, a slug rejector will be used that diverts every other nickel direct to the coin reservoir 214 so it lay-passes the switch arm llt?. f l

lf a dime is inserted, it will send an impulse to the vendingV machine by moving the coin switch 110 downwardly and it will start the motor 90 by moving the switch actuator ltll'downwardly toward the magnet 230 on the lever 222. rthe energization of the motor 9d will cause the shaft 91 to pass through a completey cycle, but Vno nickels will be paid out because the rise 314 will not move the slide Il74' far enough to the right 'to-rotate the latch 325 to slide-freeing position; and therefore when the roller SS is freed by the rise 314, the: pin 182 will be caught and held by the notch 328. The rise 306` will move theslide 174 far enough to the right to rotate the coin-responsive `element 354 to coin-freeing position Land l cause it to free the dime. .v V

lf desired, of course, thecoin-responsive element 364' could be removed; and that portion of the switch wire tti?, which extends int-o the dime passagewayl could be cutoff. In such a case the motor 90 would not even operate when a dime was inserted.

lf a quarter is inserted, the quarter Vwill supply an impulse to the .vending machine bvmoving the switch wire il@ downwardly, and it will start the motor gli by moving the switch wire 102 downwardly adjacent the magnet 2369.' The motor Btl will cause the outputshaft 94 to make one y complete revolution; and during that revolution, the rises 314;, 306, 3%, El@ and 312 will successively engage and move the roller 18S. However, the rise 314 has such a short outer radial dimension thatit'can not move the slide ldfar enough to move the latch 326 to slide-freeing A position. Consequently, only three nickels will be paid out during the, revolution ofthe shaft 94; andvthose FlG.V l. During the quarter operation, a pulse was sent to the vending machine and yfour nickels were paid out bythe slide 174. Each of the rises 322, Edd, 36S and 31d ledA to the paying out of a nickel, but the rise 312 did not; the quarter falling tothe accepted coin chute before the rise 33.2 released the slide ll74.

The four notches 295 of the'notchedV section 294iof the cam are spaced apart from each other and are spaced Vcirournferentially from the risesy 322, Ylille, 30S, Slt) and 312. Those notches are so spaced and so positioned that they will prevent clockwise rotation of the cam and lefthand movement of the slide 174 to coin-freeing position .y between the time the slide has moved close enough to the reservoir 214 to permitY a nickel to pass from that reservoir into the coirereceiving opening 1%2 of that slide and the time the next' succeeding rise of the cam moves i out of engagement with the roller 18S. ln this way, they paying out of extra nickels is prevented veven if the power tothe motor is shut off dur-ing a cycle of operation.

Ten Cen! Sales Price Y Where it is desired toV use' the change-making device of the present invention in a vending machine that vends products for ten cents, the two screws 35N? are loosened and the front section 326 of the' cam is moved .outwardly to freey the left-hand openings 325 thereof from the pin 293 on the notched portion 294 of that cam. Thereafter, the'front portion 320 is rotated in they clockwise direction coin passageway, each of said coin-responsive elements having a com-holdlng portion that Vis movable to coin` until the other opening 32S is in register with the pin y 293;' and at that time theV rise 322is adjacent the rise 396 nickels'will be paid'out as' the slide is released by thev rises 366, 3% and 31h. The coin-responsive element 343 is made so its coin-feeling portion' is normally closer to V the flange 33 of frame Ell than is Vthe coin-feeling portion verted away from the switch arm lll@ by the slug rejector. VThe second nickel will, however, engage the switch wire 1l@ and cause the switch lti to send an impulse tothe vending machine. lnthissimple and easy way, the change-making device of therprcsent invention can be set for use with vending machines selling products for ve cents or ten cents.
